嵌入式plc的发展也呈现多元化，国内外均有良好表现：德国赫优讯推出的将现场总线技术和plc技术结合的netplc很有特色;国内几年前就有华中科技大学在easycore1.00核心芯片组中加载了嵌入式plc系统软件，作为硬件平台，开发了多模人通道的嵌入式plc;还有一种发展路径是以开发plc与人机界面相结合的硬件/软件一体化为目标的平台，充分利用了case工具，结合各类嵌入式芯片的开发平台和各种输入/输出通道的硬件电路库，专为机电设备开发客制化、具有odm性质的专用plc。
个人计算机（pc）的价格便宜，有很强的数学运算、数据处理、通信和人机交互的功能。目前已有多家厂商推出了在pc上运行的可实现可编程序控制器功能的软件包，如亚控公司的kingplc。“软plc在很多方面比传统的“硬plc有优势，有的场合“软plc可能是理想的选择
很多时候，在一些大型的装配机械应用中你可能需要做启停的顺序逻辑控制。这些顺序控制在使用急停电路之前和保护通道打开之前正确地停下你的机器，很明显，通过这样控制机器的停止是有好处的。如果一个自动化过程启动以后，你想在停止机器之前允许它结束工作，特别是有一个必需的装配顺序在你的自动化机器工作周期中。一个控制停止更优于使用急停，所以你不必释放信息的跟踪，或者在周期的中间停止。
通过修改与调试后的程序称为用户执行程序，由于不需要再作修改与调试，所以用户执行程序就被固化到eprom内长期使用。
若plc控制的系统需要联入工厂自动化网络，则plc需要有通信联网功能，即要求plc应具有连接其他plc、上位计算机及crt等的接口。大、中型机都有通信功能，目前大部分小型机也具有通信功能。
